The Schedule referred to 'in these'Lettex-s Patent and making part of the same.

To all whom it may concern.-

Be it known that I, SAMUEL S. BENT, of. Port Chester, in the county of` Westchester and State of New York, have invented and made an Improvement in Metal Backs for Grates; and the following is declared to be a correct description of the same.

Grates have been made with metal backs and set into chimneys, and also in portable grates, and said backs have had openings at the upper portion, for the escape o-products of combustion.

In most dwellings, particularly in cities, the grate is seldom made use of, because of the building being heated by hot air or other means; hence, the grates become an ornament and are in place for use nextremely cold weather.

The metal ybacks for grates are usuallyv painted, and,

hence, whenevera re is lighted thev paint or varnish is burnt 0H', even by a small woodre or gas heating apparatus introduced in the grate, and the back ofthe grate cannot be cleaned, and has to be repainted, so as to appear clean and sightly for other portions. of the year. Besides this, the iron of the back does not reflect heat from the fire, but absorbs the` same and becomes heated, and this heat is not beneficial, iu

consequence of the back usually being set in brickwork. h l My invention is made with reference to ,reflecting the heat of the re into the room, and keeping the back clean and free fromthe soiled and burnt appearance usual in grates that have been usejld.-

My invention consists'in a cast-ironl 'grate-back, with an enameled surface'next the ire, said enamel being the white or light-colored vitriiied enamel like thatwhi'ch is used for the interior of pots and hollow-ware.

This vitried enamel is adapted to withstanding the heat usually coming in contact with the back above the fire-bricks, and the smooth surface can be easily. cleaned from smoke or other substance soiling the same; and, furthermore, the vitriiied back becomes a reflector, to throw out into the room heatfrom the fuel in the grate.

When the grate is not in use, this vitriied back is ,enameled upon the side next to the fire, as shown by' the double line at t', said enameling being applied for4 the purposes aforesaid.

' Removable fire-bricks, k, and a metal rim, l, above Y them, may be inserted whenever the used with a coal-fire.

The metal back for grates, coated with vitrified enamel, is a new and useful article of manufacture. I claim as my invention- A metal back for gratos, coated with vitriiied enamel, for the purposes specified, the same forming a new article of manufacture. Y
